Short-term fish predation destroys resilience of zooplankton communities and prevents recovery of phytoplankton control by zooplankton grazing.

PLoS ONE, 2019
Planktivorous fish predation directly affects zooplankton biomass, community and size structure, and may indirectly induce a trophic cascade to phytoplankton.

Changes in the structure and functionof the North Sea fish foodweb, 1973-2000, and the impacts of fishing and climate [PDF]

, 2005
North Sea environmental and biological data were analysed to examine 30-year changes in production and consumption in the fish food web. The analysis revealed that the demand for secondary production placed on the ecosystem by fish declined from ...

Zooplankton Biomass in Ponds - Determination of Biovolume and Dry Weight

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2023
The aim of this study was to evaluate the possibility of using simple screening methods to determine zooplankton biomass in ponds. Among the applicable methods, we selected sedimentation determination of wet biomass and dry biomass determination.

Net phytoplankton and zooplankton in the New York Bight, January 1976 to February 1978, with comments on the effects of wind, Gulf Stream eddies, and slope water intrusions [PDF]

, 1984
Results are given of monthly net phytoplankton and zooplankton sampling from a 10 m depth in shelf, slope, and Gulf Stream eddy water along a transect running southeastward from Ambrose Light, New York, in 1976, 1977, and early 1978.

Crustacean zooplankton dynamics in a natural riverine lake, Upper Mississippi River

Journal of Freshwater Ecology, 2017
Zooplankton communities in riverine systems are typically thought to be driven by abiotic forces. However, recent studies have shown that biological controls are capable of structuring these communities in large rivers and may become more influential as ...

The relative importance of regional and local factors in shaping zooplankton diversity in high-altitude tropical shallow lakes

Journal of Freshwater Ecology, 2020
In Brazil, although, high-altitude shallow lakes comprise large parts of conservation units and are considered highly important environments for biodiversity studies, little is known about the factors that regulate the zooplankton community.

Spatial and Seasonal Variations in the Stable Isotope Values and Trophic Positions of Dominant Zooplankton Groups in Jiaozhou Bay, China

Frontiers in Marine Science, 2022
The spatial and seasonal distributions of stable carbon and nitrogen isotopes (δ13C and δ15N) in dominant zooplankton groups were investigated in Jiaozhou Bay.

Effects of climate on size structure and functioning of aquatic food webs [PDF]

, 2010
In aquatic food webs, the role of body size is notoriously strong. It is also well known that temperature has an effect on body size. For instance, Bergmann’s rule states that body size increases from warm to cold climates.

The nutritional status of zooplankton in a tropical reservoir: effects of food quality and community structure

Brazilian Journal of Biology
The temporal variability of energetic reserves of zooplankton in the eutrophic Pampulha reservoir was investigated during two successive annual cycles. The effects of dominance of large filter-feeding cladocerans (Daphnia) and the occurrence of massive ...
